New Police TG for Denver Intl Airport on the Denver Public Safety EDACS

New Police talk group on-the-air for Denver Intl Airport on the Denver Public Safety EDACS

TG-1655

First heard on Jan 2, 2013 around 4:30 pm and has been very busy ever since. The dispatch radio or LID is 615 and 660 (probably others) and the police unit call signs start with 9XX.

I'll admit I have not been paying attention to the DPD - DIA relationship lately. Is this the DPD Airport Bureau? I am wondering if this is a new patch channel or if it is a new TG they are going to use full-time.

DIA is run by the City and County of Denver so the officers at DIA are DPD officers. All of the Denver EDACS systems have a single set of TG's so in the event of one system failing, TG duplication isn't a problem if users switch to another system for back up reasons.

I'm guessing that Aurora has some of the public safety side TG's for mutual aid reasons. I've heard DIA on Aurora a while back, but not recently.

DPD 1 Talkgroup moved to 1655 and Paramedic Talkgroup moved to 1657 several years ago on the DIA EDACS system

I wouldn't have been able to tell that happened by looking at the RR database.

Also, the last time DPD DIA police popped up on TG-1651 on Denver's EDACS was October 4, 2012 and that ended at 7:30 pm. So it has been a while since they have been on Denver's system. I am thinking that is probably why nobody submitted it to the Denver DB since it is a very rare occurrence.

Then again, I have not seen this TG on Aurora's in the last few months either. Does anyone listen to them occasionally? Where have you heard DPD DIA units? In the last few months, not 1655 on either system until Jan 2, 2013...

I have heard DIA DPD on 1655 on both Denver and Aurora's system. They are always at the airport. I wana say someone went through the radio and found the TG they wanted to talk on, just on the wrong system.

OK...
DW, 1655 has been our primary dispatch TG at the airport for at least 3 years. It's on the radio as "DIA DPD 1". I don't know why you're suddenly hearing us there, because we've been there all along.
We do now have citywide all-calls broadcast from downtown, but that's a relatively recent addition (last 6 months or so.) If you're hearing us on the Denver PS system or Aurora's, perhaps they (finally) decided to monitor us. Other than DFD's link for their purposes, we don't monitor the city or Aurora.

If a hobbyist relies on the RadioReference database for the download to the scanner, I can understand why it wasn't heard.. The TG was just placed there today. I manually added it to my Win500 list but future downloaders will have it in their radio.

Also, note the following info on those TGs on any systems not DIA... "These Talkgroups are not active all the time on this system. They are only active occasionally for roaming or backup purposes. If you wish to monitor these Talkgroups, monitor their home system"

The way my PRO-106 worked, all that needed to be done was to add the two talkgroups to the chart. I was receiving the DIA traffic immediately, it worked as though 1655 had always been in the DTRS system on my radio. It picked up all the parameters all the rest of the talkgroups possessed.

It's mind-bending to think that DPD's All-Call TG-512 (04-000) (used for armed robbery, officer needs assistance etc broadcasts) on the Denver system is simulcast onto the DIA system's TG-1655 (12-147) for DIA officers to hear (using radio ID 23) and then we can hear that same all-call re-broadcast (in the DIAs mix of police and the all-call) back onto the Denver system's re-broadcast of TG-1655.
